Although it's not yet known how his character Detective Inspector Humphrey Goodman will leave the show, it's said the hectic filming schedule in the Caribbean, away from his family, has prompted the move.

"Despite shooting on one of the most glamorous locations on the planet, being apart from wife Hannah and their two young children for most of the six month filming schedule has proved too tough for Kris," a source told The Sun .

“It’s been a hard decision, as he’s helped draw in huge figures since taking on the role, but after 17 years in the business he wants to spend more time with his family. That’s his priority now.”

Kris said: "“Death in Paradise has been an incredible experience, six months every year filming on a tropical island in the sunshine – what’s not to love! Humphrey was socially awkward and clumsy but also brilliant, I’ll miss him but it’s time to hand over to someone new and spend more time with my family. I know Ardal will do a superb job and I just hope Humphrey gets a happy ending!”

The 43-year-old actor joined the programme at the beginning of the third series, following the exit of Ben Miller.

It proved to be a success, and now Father Ted star Ardal O'Hanlon will take the lead in the show's seventh series, with his first appearance coming on Thursday night before filming for the next season begins over spring.

He said: "I am delighted to be joining Death in Paradise and exploring what’s made Mooney up and leave London for a life in the Caribbean. I’ve already had a taste of filming in Guadeloupe and can’t wait to get back.”
